CHESTNUT HILL, Mass. -- Chelsea Gray couldn't suppress her happiness after picking up her 10th assist of the game. And she couldn't hide it afterward when she talked about matching Dawn Staley's conference record with a second career triple-double.

"I'm not surprised," Duke coach Joanne McCallie said after Gray scored had 18 points with 11 rebounds and 10 assists to lead No. 3 Duke to a 90-53 victory over Boston College on Sunday. "She'll be getting a lot more of those, I'm sure."

Gray had nine points, eight rebounds and seven assists in the first half, when Duke scored 12 of the first 14 points and made it 32-5 just 11 1/2 minutes into the game. She was stuck on nine assists until McCallie told her to "make a nice pass" in the final minutes - and she did, hitting Richa Jackson for an open jumper with 56 seconds left.

That tied her with Staley, who led Virginia to three Final Fours and a NCAA title game and also won three Olympic gold medals, as the only players in Atlantic Coast Conference history with more than one triple-double.

"It feels good. It's exciting to hear that," Gray said. "When it went in, I went back and tried to hide a little smile."

Tricia Liston had 17 points, scoring 12 during a 20-0 run that put the game away, and Jackson scored 16 for the Blue Devils (13-0, 3-0 ACC), who remain the only unbeaten team in Division I. Top-ranked Connecticut lost to No. 5 Notre Dame on Saturday; No. 2 Baylor entered Sunday's game against Oklahoma State with an 11-1 record.

Kristen Doherty scored 17 points and added six rebounds for BC (6-7, 0-2). The Eagles lost their third consecutive game, including a 76-70 loss to then-No. 23 Florida State - the only other ranked team they have faced this season.

This one wasn't that close.

Duke made its first six 3-point attempts and tied a school record by making 79.3 percent of its shots in the first half to open a 55-20 lead. BC scored the first eight points of the second half, but never got within two dozen points.

"We didn't back down. We went right at them, and suddenly Duke realized, `Hey, we've got a basketball game on our hands,'" BC coach Erik Johnson said. "Unfortunately, Duke's so good, and played so well in that first half that the game wasn't really in question by the time we got it rolling."

Trailing by 35 at the half, Doherty hit a 3-pointer to open the second and Nicole Boudreau drove to the basket for a layup, prompting McCallie to call a timeout. Boudreau made a free throw, then Tessah Holt made a pair as the Eagles continued to force turnovers.

"I was just very mad," McCallie said. "I don't think it put a scare, two turnovers in a row is just very silly."

BC had several more chances to cut the deficit further but couldn't make its shots. Gray scored on a foul line jumper with 16:25 left to play to end the Blue Devils' scoring drought.
